T Extended Weakly Contractive, Kannan, and Geraghty Mappings Fixed Points, Equivalences,
Fatemeh Fogh, Sara Behnamian
We develop a unified T-extended framework for weakly contractive, weakly Kannan, and Geraghty classes of self-maps S on a metric space (X, d), where distances are measured on the a…
Interval-Censored Survival Analysis of Grapevine Phenology: Thermal Controls on Flowering and Fruit Ripening
Sara Behnamian, Fatemeh Fogh
European grapevine (\textit{Vitis vinifera} L.) is a climate-sensitive perennial whose flowering and ripening govern yield and quality. Phenological records from monitoring program…
Isomorphisms, Moduli, and Cohomological Dimension for Twisted Triangular Banach Algebras
Sara Behnamian, Fatemeh Fogh
We introduce and study twisted triangular Banach algebras T_sigma(A,B;X), built from Banach algebras A,B, a Banach A-B bimodule X, and a pair of automorphisms sigma=(sigma_A,sigma_…
Best Proximity Points for Geraghty-Type Non-Self Mappings with a Registration-Inspired Alignment Model
Fatemeh Fogh, Sara Behnamian
We study Geraghty-type non-self mappings within the framework of best proximity point theory. By introducing auxiliary functions with subsequential convergence, we establish genera…
